[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Reference as follows Figures 1-8 The utility model is described as follows:

[0037] Embodiment: A shoe whose size can be adjusted according to the thickness of the foot comprises a sole 1 , an upper portion of the sole 1 is provided, and the upper portion comprises a first upper portion 2 and a second upper portion 3 .

[0038] The first vamp 2 is annular, with its lower end fixedly connected to the edge of the sole 1. The first vamp 2 is made of leather. Leather offers many advantages, such as good texture, durability, and a stylish appearance, giving these shoes the style and advantages of leather shoes. The lower end of the first vamp 2 is fixedly connected to the edge of the sole 1. This connection ensures a secure bond between the upper and sole 1, preventing them from separating during walking and other activities.

[0039] The second upper 3 is sheet-shaped, with its front, left, and right sides connected to the upper side of the first upper 2. The second upper 3 is made of fabric. Compared to leather, fabric has greater deformability. This means that when the wearer's instep is high, the fabric upper can stretch and adjust to the shape of the foot, providing a more comfortable wearing experience. Furthermore, fabric uppers are generally breathable and soft, reducing friction and pressure on the foot.

[0040] The rear end of the second vamp 3 is spaced apart from the rear end of the first vamp 2 to form a shoe opening for the foot to enter. The front, left, and right sides of the second vamp 3 are connected to the upper side of the first vamp 2, and the rear end is spaced apart from the rear end of the first vamp 2 to form a shoe opening for the foot to enter. This connection method not only ensures the integrity of the vamp, but also facilitates insertion and adjustment of the foot. Once the foot is inserted into the shoe, the second vamp 3 can be adjusted according to the height of the instep, allowing the shoe to better adapt to the needs of different wearers.

[0041] This shoe's ability to adjust to foot thickness is primarily due to its unique upper structure. When the wearer's instep is taller, the fabric second upper (3) deforms under pressure, expanding the shoe cavity to accommodate the height of the instep. Specifically, the following factors work together to achieve this size adjustment:

[0042] Fabric Properties: The fabric has good elasticity and ductility, and can stretch and deform within a certain range. When the instep applies pressure to the second upper 3, the fabric will deform accordingly based on the magnitude and direction of the pressure, thereby providing more space for the instep.

[0043] Upper Connection: The connection between the second upper 3 and the first upper 2 ensures that deformation of the second upper 3 does not affect the stability of the entire upper. Furthermore, the leather material of the first upper 2 provides support for the second upper 3, preventing excessive deformation.

[0044] Shoe opening design: The shoe opening design allows the foot to easily enter the shoe and can be adjusted as needed during wearing. When the instep is high, the shoe opening can be appropriately expanded to facilitate foot entry and adjustment.

[0045] Advantages:

[0046] Comfort: By adjusting the size based on foot thickness, this shoe provides a more comfortable wearing experience. Whether you have a large instep or a normal instep, you can adjust the shoe size to your needs to reduce foot pressure and discomfort.

[0047] Personalization: Everyone's foot shape and needs are different, and the adjustability of this shoe can meet the personalized needs of different people. The wearer can adjust the size of the shoe according to their preferences and actual conditions to make it fit their foot shape better.

[0048] Fashionability: The first upper 2 is made of leather, which has the style and advantages of leather shoes and is fashionable and beautiful. At the same time, the second upper 3 made of fabric also adds a casual and comfortable feeling to the shoe, making this shoe suitable for both formal occasions and everyday wear.

[0049] The second upper 3 includes an outer fabric layer 31 and an inner fabric layer 32, a thermal insulation layer 33 is provided between the outer fabric layer 31 and the inner fabric layer 32, the edges of the outer fabric layer 31 and the inner fabric layer 32 are fixedly connected, and the outer fabric layer 31 and the inner fabric layer 32 are fixedly connected by a grid-like stitching 34.

[0050] The outer fabric layer 31 is typically made of a textile material with a certain degree of wear resistance, water resistance, and aesthetic appeal. It not only protects the thermal insulation layer 33 and inner fabric layer 32, but also adds a touch of style to the shoe. The color and pattern of the outer fabric layer 31 can be selected based on different design requirements to meet individual consumer preferences. As the outermost layer of the shoe, the outer fabric layer 31 protects against external environmental factors (such as dust and moisture). It also provides structural support for the entire second upper 3.

[0051] The inner fabric layer 32 is typically made of a soft, comfortable, and breathable fabric material. It comes into direct contact with the foot, providing a comfortable feel and reducing friction and pressure. The material of the inner fabric layer 32 is typically highly absorbent, absorbing perspiration and keeping the foot dry. The inner fabric layer 32 is primarily responsible for direct contact with the foot, providing a comfortable environment. Its softness and breathability enhance the wearer's comfort and reduce foot fatigue.

[0052] The thermal insulation layer 33 can be made of a variety of thermal insulation materials, such as wool, cotton, down, etc. These materials have excellent thermal insulation properties, effectively blocking out cold air from the outside and keeping the feet warm. The thickness and material of the thermal insulation layer 33 can be selected according to different seasons and usage requirements. In cold seasons or environments, the thermal insulation layer 33 can provide additional warmth to the feet, preventing them from freezing. Its presence not only allows for size adjustment but also provides warmth, enhancing the practicality of the shoe.

[0053] The outer fabric layer 31 and the inner fabric layer 32 are fixedly connected at their edges: This connection can be achieved by sewing, gluing, or other methods to firmly bond the edges of the outer fabric layer 31 and the inner fabric layer 32 together. This prevents the outer fabric layer 31 and the inner fabric layer 32 from separating during use, thereby ensuring the structural integrity of the shoe.

[0054] The outer fabric layer 31 and the inner fabric layer 32 are connected by a grid-like stitching pattern: This grid-like stitching not only further secures the outer fabric layer 31 and the inner fabric layer 32, but also enhances the shoe's breathability. This grid-like stitching allows air to circulate within the shoe, improving breathability and reducing the feeling of stuffiness on the foot. Furthermore, the grid-like stitching enhances the shoe's aesthetics, adding a unique design touch.

[0055] In order to enhance the adjustment capability of the second vamp 3, the present application provides the following two implementation structures:

[0056] Implementation structure 1: The left and right sides of the rear end of the second upper 3 are spaced apart from the first upper 2, and the left and right sides of the rear end of the second upper 3 are connected to the first upper 2 via an elastic sheet 4. The elastic sheet 4 has good elasticity and can stretch and shrink within a certain range. When the height of the instep changes, the elastic sheet 4 can deform accordingly according to the magnitude of the pressure, thereby providing additional adjustment capabilities for the second upper 3. The elastic sheet 4 can firmly connect the second upper 3 and the first upper 2 to ensure that they will not loosen or fall off during use. At the same time, the elasticity of the elastic sheet 4 can also ensure the flexibility of the connection part and will not affect the overall wearing experience of the shoe.

[0057] For those with large variations in instep height, implementing structure 1 can provide better adjustment capabilities to meet their wearing needs in different situations. For example, some patients with swollen feet, pregnant women, or people who stand for long periods of time at work can all benefit from this design.

[0058] The elastic sheet 4 is connected in such a way that there is a certain amount of space between the left and right sides of the rear end of the second upper 3 and the first upper 2, making it more convenient and quick to put on and take off the shoes. This design is particularly suitable for occasions where shoes need to be put on and taken off frequently, such as hospitals, gyms, etc.

[0059] Implementation structure 2: The front, left, and right sides of the second upper 3 are connected to the upper side of the first upper 2 via elastic bands 5. This connection method allows the second upper 3 to be adjusted in three directions via the elastic bands 5, further improving the shoe's adaptability to different foot shapes.

[0060] The elastic band 5 is located on the inner side of the first upper 2 and the second upper 3. This design offers several advantages. First, the shoe's appearance is more streamlined and aesthetically pleasing, without the presence of the elastic band 5 detracting from the overall design. Second, the inner location of the elastic band 5 provides better protection for the foot, preventing it from being snagged or damaged by external objects during walking or activities. Furthermore, the inner location allows the elastic band 5 to be closer to the foot, enabling it to more effectively perform its regulating function.

[0061] When the elastic band 5 is in its natural position, the edge of the second upper 3 is in contact with the upper edge of the first upper 2. This design ensures that the shoe's appearance is neat and tidy, without gaps or looseness. Furthermore, this close fit helps improve the shoe's stability and reduces the movement of the foot within the shoe.

[0062] As the thickness of the wearer's foot changes, the elastic band 5 stretches or contracts according to the amount of pressure. If the instep height increases, the elastic band 5 stretches, expanding the shoe cavity to accommodate the change in foot size. Conversely, if the instep height decreases, the elastic band 5 contracts, making the shoe fit more snugly and improving wearing comfort.

[0063] The elastic band 5 is U-shaped, which can better adapt to the structure of the shoe and provide more uniform elastic force. The U-shaped elastic band 5 can work in three directions simultaneously, ensuring that the second upper 3 can be effectively adjusted in all directions.

[0064] The two sides of the elastic band 5, along its width, are sewn and fixedly connected to the first upper 2 and the second upper 3, respectively. This secure connection ensures that the elastic band 5 will not fall off or become loose during use. Furthermore, the sewing and fixed connection provides a smoother connection between the elastic band 5 and the upper, reducing friction and discomfort on the foot.

[0065] Implementation Structure 2 is suitable for people with different foot shapes, especially those with unusual foot shapes or large variations in instep height. Whether it is flat feet, high arches, or other foot problems, this design can provide better comfort and adaptability.

[0066] During exercise, the foot is subject to significant pressure and impact, and the foot shape may also change. The elastic band 5 of the second embodiment can automatically adjust to the changes in the foot shape, providing better support and protection for the athlete. Therefore, this shoe is particularly suitable for running, basketball, football and other sports.

[0067] The ground surface of the sole 1 is provided with a groove 61, within which is an anti-slip block 62 having a greater hardness than the sole 1. The groove 61 provides a mounting location for the anti-slip block 62, allowing it to be securely embedded in the sole 1 and prevent it from falling off. The anti-slip block 62 has a greater hardness than the sole 1, which allows it to better withstand friction and pressure when in contact with the ground and is less susceptible to wear. The high hardness of the anti-slip block 62 ensures that it maintains good anti-slip properties during long-term use. The sole 1 is made of rubber, while the anti-slip block 62 is made of tendon.

[0068] A soft covering 71 is provided on the inner side of the first upper 2, and a mesh layer 72 is provided on the inner side of the soft covering 71. The soft covering 71 is typically made of a soft, elastic material, such as sponge, latex, or memory foam. These materials provide excellent cushioning and support, reducing friction and pressure between the foot and the upper. The primary function of the soft covering 71 is to enhance the comfort of the shoe. When the foot contacts the upper, the soft covering 71 absorbs some of the pressure, making the foot feel softer and more comfortable. Furthermore, the soft covering 71 provides a certain degree of warmth, especially in cold weather, by effectively blocking out cold air and keeping the foot warm. The mesh layer 72 is typically made of a breathable material, such as polyester or nylon. The mesh's porous structure allows air to circulate within the shoe, keeping the foot dry and comfortable. The mesh layer 72 also has excellent strength and wear resistance, making it able to withstand the wear and tear of daily wear. The primary function of the mesh layer 72 is to enhance the shoe's breathability. During wearing, the feet generate sweat and heat. If the shoes are not breathable, the feet will become damp, hot, and even breed bacteria. The mesh layer 72 allows air to circulate freely, dissipating sweat and heat from the feet in a timely manner, keeping the feet dry and clean.

[0069] Both the elastic sheet 4 and the elastic belt 5 can be elastically stretched.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
